The Wren burger is good. It reminds me of a good whopper.
However their entire menu is very spicy and they never ever tell you! Even when you ask. On several occasions i've asked the if it's spicy and they've said no. Then the food is riddled with hot peppers or chilis. When you confront them about it they don't give a s$&@ either. On one occasion they charged me for the replacement dish. Which is bad service.
