I have been to the gun for both a few drinks in the evening and lunch and both were superb. For lunch we had an amazing view of the O2 arena and river in a delightfully naval themed room. The food was excellent (both lunch and canapes in the evening) and the service was excellent for drinks. A bit pricier than the average pub, but worth every penny. If you go for lunch during the week them will also offer you a free car service to and from the restaurant.
