It's funny but we actually have a really good sushi place that just got added around here. Best part is that they have $25-50-75-100 coupons. I think to use the $100 you have to spend $225 on the total bill and they add 18%, but it's a good deal when you have a 6 hungry people in the mood for sushi.
Some of the mom and pop places I've gone to in the past weren't cheap, but the food was still good. Just because a place isn't corporate doesn't mean it isn't good food. I like grabbing one of these coupons when I'm travelling on vacation...it adds a little excitement to the trip and saves some cash when you are eating out 3 meals a day anyhow. I wasn't let down the last time. I ended up wish some awesome Thai food and some really good pizza at another place.
