Food at the River Oyster Bar is still top, but prices are getting a bit out of whack. On top of very high price the restaurant charges a 20% service fee and leaves space for additional tips, with the waiter putting a smear when an additional fee is tot given. We ate very well with the exception of a crab starter which was definitely not up to expected standards. We tend to go to the Oyster Bar whenever we visit Miami but if prices continue their upward spiral, we are not sure we'll return. It is about time that Restaurants recognize that a a Tip is to recognize excellent service, not something that has lately become compulsory.
