It is very common for a bar or a small local restaurant to have 8 to 12 different kinds of tapas in warming trays with glass partitions covering the food. They are often very strongly flavored with garlic, chilies or paprika, cumin, salt, pepper, saffron and sometimes in plentiful amounts of olive oil. Often one or more of the choices is seafood (mariscos), often including anchovies, sardines or mackerel in olive oil, squid or others in a tomato based sauce, sometimes with the addition of red or green peppers or other seasoning. It is rare to see a tapas selection not include one or more types of olives, such as manzanilla or arbequina olives. One or more types of bread are usually available to eat with any of the sauce-based tapas.
