The grill is the main focus of you outdoor kitchen, its where the food is cooked. Everyone likes to hang out at the grill and now grilling can be an event for everyone to enjoy.
Size of your grill will depend strictly on how much food you prepare at any given moment, if you cook for a large group of people on a regular basis you may want to choose the 48” Gourmet grill with 90,000 BTU’s, and for those that cook for a more moderate group of people the 37” Gourmet grill will work just fine.
