We spent 9 days in Maui 3/27-4/5 (myself, husband, and son). My husband and son have Celiac's disease so must eat gluten-free, so I thought I would provide some info on our experience for future residents - paying back to the forum all the help we have gotten :)
Overall we found that Maui restaurants are very gluten-free aware. Many that we ate at did not have dedicated gluten-free menu's but very often indicated gluten-free choices right on the regular menu and I don't know that we went anywhere where the server did not know what we were talking about. Most knew right away and if they didn't they were very good about going to ask someone and double/triple checking with us to make sure everything was good. I personally thought it was a better experience than what we sometimes get at home in the Midwest or that we have gotten traveling to other places. Neither DH or DS ever got sick or had any cross-contamination issues (although I have heard it happens on Maui just like anywhere else - but nowhere we ate).
We were not in a condo so did not do a lot of shopping, but there are a few staples we always need.
- We shopped at two Natural Food stores - Mana Foods in Paia and Hawaiian Moons in Kihei. Both had decent gluten-free selections. Both carried Udi's brand bread, muffins, etc. and we like to buy the muffins for breakfast on the go. If you have never had Udi's bread, muffins, etc. it is the best gluten-free brand we have ever had. We buy it at home all the time. Mana Foods seemed to be larger and have a better selection. We found some frozen gf donuts that were good and they had a few freshly baked items in their bakery as well (didn't try them).
- Safeway and Foodland in Kihei both had a few gluten-free items in the grocery section. No Udi's and we did not look for any other bread or frozen items there.
- We found the large box of Crunchmasters gf crackers at the Maui Costco (never been to any Costco that does not have them). We bring these along with cheese and salami for lunchtime snacks on the beach or on the road instead of sandwiches.
Restaurants in Kihei:
Coconuts Fish Cafe - They had 2 or 3 gf items designated on their menu. DH had fish tacos and DS had the fresh local fish plate (fish with rice). The fish can be cooked multiple ways and both said it was very good.
Maui Brick Oven - this is a dedicated gluten-free restaurant! It is a pizza place (pizza was very good - I liked it too and could not tell it was gf and I usually can!), but they also have a few other items. They had beer-battered (obviously gf beer) mushrooms as the daily special and they were AWESOME - better than the pizza. Don't know if they have these every day but beer-battered onion rings are on the menu so I'm sure they are good also.
Stella Blues - can't remember if they had a gf menu but they accommodated nicely. DH had steak which he said was VERY good and DS had a shrimp cocktail and rice. Shrimp was good too.
Fred's Mexican Cafe - as with most mexican - you can order many things gf by having corn tortillas. If I recall there were some meats on the menu they could not have but the server was knowledgeable. Their chips were not gf (share same fryer with other things). Food was just ok - probably would not go back but they didn't have any contamination issues.
Kihei Caffe - went here twice for breakfast - no special items marked as gf but both DH and DS ordered normal breakfasts of eggs, potatoes, bacon, etc. with no bread. It was good and servings were large enough even without the extra carbs for DH. DS said it was the best bacon he ever had!
Restaurants in Wailea:
Fabiani's - ate here for breakfast - nice omelets, eggs, etc. No gf bread or items in their bakery but the breakfast was good and reasonably priced for Wailea area.
Mulligans on the Blue - had dinner here the last night - very nice atmosphere and LOTS of gluten-free options. DH had ribs (not a gluten-free "given" everywhere due to bbq sauce) which he said were really good. They also have gf pasta here and DS had gf mac & cheese which he liked as well.
Restaurants in Lahaina:
Cool Cat Cafe - burger joint - nothing special gluten-free but they had burgers without buns and they were fine. Kind of a fun atmosphere - good for people-watching.
Star Noodle - the server actually came to the table with a highlighter and highlighted the gf items (there were about a half dozen things which is a lot considering overall size of menu). We ordered Pad Thai, Singapore Noodles, Roasted Mushrooms, and Vietnamese Crepes and shared everything. It was all really good - probably best meal we had on the island and even my picky DS agreed with that. Definitely lived up to their reviews and we learned why everyone raves about this place! Wanted to go back but never had a chance.
Cheeseburger in Paradise - much like Cool Cat nothing special but burgers without buns were fine here also (although Cool Cat Cafe's burgers are better). Atmosphere here was fun though.
Restaurants in Paia:
Flatbread Company - we did not go here but I mention because I do know they have gf flatbread and I believe cook separate from the others. We stopped and looked at the menu and the gf was $6 extra! I know things are more expensive in Maui and you usually have to pay an upcharge everywhere for gf pizza/flatbread crust but anything more than $2-$3 is a bit ridiculous - so we passed.
Rock & Brew - this is a new restaurant in Paia and it was very good (went here twice). They have gf pizza crust they make themselves (in their LA store - they freeze it and ship it) and it was very good. They make it square so they don't get it mixed up with their other pizzas. No gf bun for the burgers but they serve in a lettuce wrap, and best of all for DH - he was very happy that their french fries were in a gf fryer!
Ululani's - all of the Shave Ice ingredients (ice cream, flavors, toppings) are gluten-free. Can't go to Maui without going here at least once! (we went 4 times).
Local Boys Shave Ice - went here once and they are also good but not as good as Ululani's. No issues with gluten.
Coconut Glen's Ice Cream on the Road to Hana - really good ice cream - not only gf but also dairy free (made with Coconut Milk).
I think that is about it. Hope this is helpful to others and if you have questions feel free to PM me.
