Hands-down winner for lunch if you like mainly but not exclusively vegetarian is Slice  at the Model Niland Centre on the Mall. Strictly lunchtime hours but brunch on Sundays, closed Mondays but not always on Bank Holiday Mondays.

Osta the excellent coffee stop with light meals and wine bar in the evenings (Thurs to Sat ?) on Hyde Bridge (down the lane adjacent to Barton Smyths sports shop) .

 

Out of town snacks. Favourite place is The Stables adjacent to Yeat's Grave Drumcliffe, shop / coffee shop. All fresh all homemade and casual and reasonable. Day time only, 7 days a week.

Lunch again til late afternoon- Lyon's Cafe at the top of O Connell st. Sweet long enduring venue with daily specials to suit all tastes and everyones budget, self service, have a meal or a snack. Cakes are especially good.

Formal dining. French restaurant Montmartre in the Market Yard, reliable traditional french food at the the more bearable end of the price range for this sort of food in Ireland.

For a more casual but still considered dining experience, where children are welcome the  "Silver Apple" the new restaurant (evening meals)  bearing the name Raffertys" on the exterior , hearty delicious French inspired food for everyone, including ( a not very French) children's menu, but child friendly. For a more informal atmosphere and distinctively lower prices than the other options. Located directly opposite Sligo bus and train station on the corner of Wolfe Tone Street and ? Lord Edward Street.

For another formal dining experience Coach Lane above Donagheys pub near the train station comes recommended but is definitely credit card territory.

Self catering? Try  the Gourmet Parlour, Bridge Street, for sandwiches, bread, cake and take out meals from Ballymaloe trained chefs who make it better than anyone else ever could. Daytime only, Monday to Saturday.  Also a new French bakery also on Tobergal Lane adjacent to Tobergal Lane Cafe.

For the only fast food place worth going to Mollys on Markievicz Road, ie across Hyde bridge from the Glasshouse Hotel. Serious portions of delicious homemade chips, a far cry from the usual reconstituted potato encountered elsewhere.

 "Laura's Pub" in the village of Carney, around 15 Minutes from the town HAS to be mentioned! Laura's Pub sells delicious world class cuisine. Starters include French soup, mushrooms with chicken stuffing and pepper sauce, and crab claws. Examples of main dishes are Supreme of chicken caprini with goat cheese (highly recommended), and steaks. It's a family run business and they're the nicest bunch of people you could ever meet and it's resonably priced. All orders come with vegetables which are freshly picked from the family's own garden just down the road.
