C.,
I don't know exactly where you are looking, but I got married in the Southlake Grapevine area almost 7 years ago. We used a place called "the Ranch of Lonesome Dove" The drive makes you feel like you are going out in the middle of nowhere, but once you get there you are overlooking the lake. They have a gazebo for an outdoor location, and a large hall for an indoor wedding space and reception, they also have a small chapel which we didn't use, but it is adorable if you are wanting a small indoor service. It is not a real formal feeling place, but can be beautiful. It was perfect for my family because we are not formal people, we are down to earth, family oriented, comfortable people. It is run by a family that started doing this after they planned their daughters wedding and realized how pricey things could be. They can do the catering, they can recommend photographers, and people for the wedding cake. You may even be able to do all of it through them now, when I got married all they had were business cards of other people, I had to find my own photographer and cake person. But they did my food, and decorations, they set up, and clean up, my parents did help with some of the clean up because the extra food they got to take home, which worked out well with all the company they had for the rest of the weekend. They are very nice people and a beautiful location. I know there prices have changed since I got married there, but when I was looking they were very reasonable. They had different packages to choose from depended on how long you wanted to be there, what type of decorations you wanted, did you want a horse and carriage or not, and many details that I hadn't even thought about. I am a bargain shopper and for that size of a space and that kind of location, I couldn't find any better. My husband and I paid for everything ourselves (except myfamily paid for my dress, accessories, and alterations.) So we were budget shopping. There # is ###-###-#### address is 2299 Lonesome Dove Rd Southlake Texas. They have a website now also www.theranchoflonesomedove.com
Some of those pictures are old, They have a concrete sidewalk leading up to the gazebo, which they didn't have when I got married there. And alot of their pictures look western, but you don't have to do western, our wedding was not western at all it was more like garden theme.
I hope this helps, don't wait to long to book though, we went to book ours just over a year in advance and we had to do a friday wedding instead of saturday because the saturday for the weekend we wanted was already taken.
Good Luck and have fun.
