I ordered a planted chicken dish (so vegan and no gluten but not marked glutenfree) at it was pretty nice. They are definitely more authentic so a little more spice even in the non-spicy dishes which is fine for me but maybe not for ibs! I didn't have to ask about an allergy-menu, the allergens were already marked on the one I got which was nice. Vegetarian and vegan was no problem and most dishes were gluten free as far as I saw, but Cross-contamination could still be an issue, I did not ask but told the waiter in advance (it was pretty full but service was fast, pretty loud though). Did not have any symptoms this far :)
