Burger Bar is quite yummy and it has a lot of excellent options (especially if you're allergic to gluten/wheat etc) and delicious toppings. I really enjoy it.
It's got a great vibe and the servers are really lovely. Also, you can order a mix of half fries/half sweet potato fries. Amazing!
As much as I like Burger Bar, I miss Rice Bar. Burger Bar used to be rice bar, which had many delicious bowls of foods. I would not travel across the city to go to Burger Bar, but if I was in the neighbourhood, it's a solid place for a burger.
