Hello, I'm new to Chowhound. Hoping that I can get advice on finding a great restaurant in the Westside - Santa Monica area. My family wants to plan a surprise bday dinner to celebrate our grandma's 79th. I'm very consciencious about cleaniness, service, decor and of course, it's all about the food!!! Since this is a celebration, it's about atmosphere! We are open to Mexican and Italian cuisine. It's for a party of 25 (which includes five children ranging from 3-11). Price points are from $15-$25 per plate. Any suggestions are greatly appreciated. Thanks.
