My husband and I are looking for a casual venue - we originally thinking maybe a pizzeria -- to celebrate our twins' first birthday. Our house is too small to accommodate the 15 or so adults we anticipate will join us and we'd like to avoid spending the party serving guests and the clean up later. Probably no other kids than ours. We pictured having pizza, salads, a cake with some family and great friends. Say 4 ish to 6ish (so not prime dinner hour). The stumbling block is thinking of places that have enough tables they can put together for us or some space they can set aside to put us in. Any ideas?
