Depending on where you are travelling to...it would definitely be more exciting to visit local grocery stores and buy things from the deli and sit in a park and watch the people go by! In my experience, there are a lot of horrible restaurants out there that lure tourists in only to be overpriced, poor service and lousy food. If you don't have good recommendations, it can be hit and miss and very disappointing. We wince paid 70 EUR for 2 burgers and a salad in Paris and when I scoffed at the bill the waiter said 'it's not mcdonald's!! Just make sure you know how to say "cooked" in the local language
This summer I actually had to 'oink' to find out if what I was pointing to was pork in Prague! It's all part of the fun of budget travel!!
