My mom is coming the end of this month. She's staying over the weekend. Yay! We need a new place for champagne brunch. We've gone to Blue Mesa Grill twice already.
Trulucks is amazing, Lawrys is also good. If you want something a bit more casual Nick and Sam's grill is good but downtown. Always Breadwinnerst is yummy but no sure if thry do champagne. Next on my list to try is Jasper's in Plano.
I second Lawry's. They have a great brunch (complimentary champagne or mimosa) with a two course meal (salad/soup and your entree). They have a wide variety of entrees - most less than $20. It's our go-to "nice brunch" location.
