Oysters are very popular in New York and much cheaper than in Britain. The culture here is to go to a bar and have some oysters while having a drink in the early evening.
Millers Tavern in Williamsburg does $1 dollar oysters every day from 4pm. We had a dozen between us.
A good drink I found to have with the Oysters in Millers was a left hand milk stout a drink which goes very well with oysters. Milk stout is a stout similar to Guinness but it has lactose sugar from milk added when brewing. Yeast cannot break down lactose sugar so it gives the stout a creamier body and a much sweeter taste. It's nice but you can't really drink more than two without feeling full.
We also went to the most famous place for oysters in New York the Oyster Bar at Grand Central Station . It is a crazy busy tourist destination but worth it for the oysters and the station itself is beautiful. The prices at the oyster bar are a bit higher than other places but they do have a huge variety from all across North America.
We had the house oyster platter of eight oysters for about $20 and I also ordered two oysters from Prince Edward Island in Canada as that's where my grandfathers family is from. They cost about $3 each
We got a huge selection of condiments to go with our Grand Central oysters: Lemon, vinegar, salt, pepper, tabasco, horseradish, some cheap looking oyster crackers and tomato ketchup. The ketchup seemed a bit odd and I couldn't really work out how it would go with the oysters. I just like to put a bit of lemon juice and a splash of tabasco on mine. The oyster bar also has a full menu of meals but they are very expensive compared to the rest of the city's restaurants so I'd recommend going somewhere else for a full meal.
