I like when a restaurant has this friendly feel about it and you just know you're going to come back here again. I prefer restaurants when it's not too busy and you can actually have a conversation, but I like to go to some of those where there's live music accompanying the meal. I find it very important that the staff is friendly. It puts me away if someone is working there as if they were forced to do it. I prefer short menu's like this one:
