First may I ask where you intend on staying. Jomtien? Pattaya, or North of the city.
    The Jomtien Pratamnak area is home to many fine restaurants the list is quite long.
    It does depend on how much you would like to spend for dinner as well. (as always)
    There are a few Italian eateries you may enjoy, "PAN PAN" which is a chain you'll
    the Restaurants throughout the city. There is a little Mexican Restaurant "Mikes" located
    off Soi 5 on the way up the hill into Pratamnak. (try Mikes the food and the Margarita's
    are quite good. Plus there are many higher end Restaurants you'll want to explore in this 
    area. Please peruse the page and happy eating!

MK, is in most local malls. It consists of some favorite Thai dishes.
They will give you a "hot pot", which you'll buy pork, chicken, whatever you want, then cook it in the hotpot yourself. It's great.
Thai girls love to be taken to "MK".

Cafe Le Mar
This is a great little restaurant in south Jomtien, at 251 Moo 12.
The pizza is good, generally inexpensive. They will also serve you on the beach. (across the street)

An interesting Mcdonalds on Sukhumvit. The, juxtaposition
of the old and new, the culture clash, the Mcdonalds with the warriors is quite a site.

Not only are there Mcdonalds in Pattaya, but, also, McDelivery! So, they are open for 24 hours and they will delivery via motorbike to where-ever you'd like.
