Tapas is a form of Spanish appetizer, but makes a great communal meal due to its variety and portion size, with diners able to sample an array of food before feeling full. Served on bread, Tapas can be either warm or cold, and popularly involve seafood, sausage, garlic, olive oil, tomatoes and cheese. So gather some good company, sit glass with a back of Sangria, and try out some of these restaurants in the St. Louis area.
