I will be in Denver with some of my college friends for a few days with no car. We need to find a couple places within walking distance of the convention center that won't break our budgets! Not looking for fine dining here, maybe sandwiches, pizza, take out, etc. I'd like to find something local instead of chains we see everywhere. Anything recommended? Anything to avoid? If nothing nearby, are there places that deliver to the hotels around the convention center? Thanks for the help.
