This seems like a popular spot for takeout and a quick lunch or dinner bite. Why isn't this listed on Tripadvisor?
Probably because no one has bothered to review it.
You can go to the review area and post the name there. If its not yet listed they will tell you so and allow you to post pertinent info--street , phone number etc.... and then leave your email...and they will contact you once the place has been vetted.
Just too many businesses to have them all........and I have had to do this many times in order to review places I felt for the good or the bad needed to be listed here.
I pretty much have done that.
I await response from Tripadvisor
