This is the restaurant inside of OMSI. It's reasonably priced and they have healthy options. The kids usually do get the pizza (which isn't so healthy ) but always finish it. They make it in a pizza oven in the Hearth section. Salads, wraps, sandwiches,...More

Inside of the museum. The sandwich I had was decent but it was 10.00 for a Tuna salad sandwich. It is very catered to the eco friendly crowd. The staff was friendly and they did clear off tables quickly.

Sandwiches are decent. Pizza is quicker. Finding seating for a large group is a challenge on weekends and other busy days. Plan to sit with strangers.

There are several options from wood fired pizza to sandwiches. The catch is there are different stations for each. Explore before you buy. Also, the pizza is awesome.

We don't always eat at Theory when we visit OMSI, it we have eaten there on a few occasions and have always enjoyed our meal. Then menu items are a bit different from your ordinary Cafe, but there are some standards for your more picky...More
