I have been to Jump a number of times over the years, as it is a popular lunch spot situated in the middle of the financial district. The service is great and the food consistently good. The mushroom soup (a staple at O&B restaurants) is a must.
The patio is busy in the summer. Thursday is the busiest night with the after work crowd of the financial district. However, the dining room can get quite noisy due to the large glass windows which makes the conversation of patrons seem even louder. Having said that, the atmosphere is lively and energetic. Definitely worth a visit.
