Very average to me. Almost tasted like the boxed patties that you can buy at grocery stores. I had the medium spicy beef patty and also tried the chicken curry patty. Nothing special about the beef patty. The chicken curry patty had very little filling and didn't have a very strong curry taste. In terms of the spice level, I would say they are on the milder side of spice.
If you're looking for a good patty, I would recommend Randy's or Allan's.
