A fun place to eat for a rowdy, loud group of 6, approx. $20-$30 per entree? Good drinks=IMPORTANT!

It's been YEARS since I've been to Vegas. My friends are going to Vegas in March and I told them I would help them find a good place for a birthday dinner. This is a very rowdy crew, 6 people total, they are trying to keep the budget down to about $20 per entree plus drinks, dessert tip etc. Is $20 per entree even possible in Vegas these days? The most important part of the dinner will be a fun place to accommodate this LOUD bunch, a fun atmosphere/good views. Good drinks and friendly staff are a must. I know this is asking a lot, so if the entree price must go up (to maybe $30.00 per entree), I understand. They are open to any type of food except sushi. PLEASE HELP!! :( Any suggestions?

P.S.
They are staying on The Strip and will not have a vehicle
