My wife and I stopped in here for dinner a few times this past week.
I am severely allergic to shellfish, and touring within the eastern provinces of Canada can prove difficult when searching for a restaurant that can or will accommodate my allergy. The Gypsy Tea room's staff were very kind and super accommodating. We noticed there were many gluten-free and nut free options for everyone. I would say they can confidently add shellfish-free to that menu as well!
A few things we tried from there include;
Calamari.. lightly breaded, with red onions and a delicious house-made Tzatziki sauce.
The Cajun chicken fettuccine - kept coming back for this one, probably one of the best pastas around.
Oven roasted red pepper soup - absolutely perfect balance of salty and creamy/sweet. Topped with fresh crumbled feta cheese and some Chile oil... soo good.. chefs kiss!
Even their French fries were done to perfection.
Would 10/10 recommend trying this restaurant if your touring St. Johns and looking for something other then pubfare.
