I'll be seeing my DC at uni in Cambridge in a few weeks, also with my parents, and need to plan somewhere for lunch. We'd like it to be pleasant, not too noisy or tightly-packed / crowded, probably bookable so we're not waiting in a queue, but feels good for a student as well as us from the older generation, so can be a bit trendy / fun. Also pretty central. DC likes nice food. Any recommendations please?
