Trying to find gluten and soy free food (they also cater for other allergies) that isn't boring and caters for your friends? I can recommend Bar Burrito. Being not that au feit with digital I needed the cheerful, patient and friendly help of the serving lady. For those digi-whiz persons, you can scan a QR Code and select your allergies. You will then get a detailed breakdown of the menu and what is safe for you to eat.
I ate loaded Nachos with meat and vegetable toppings, the nachos were crispy and dry, not only at all. They had a good choice of Mexican beers and soft drinks. I'm fully recharged, ready for more shopping in St. David's Centre! Recommended.
