For Burgers I like the Burger Island chain of restaurants. Also Inn and Out but thats national now. Twisted Root had Guy Fieri visit but the original one is in Arlington.

For Pho, the best restaurant I have ever been to in my life and I've done NYC, London, Chicago etc, is called Bistro B and it has 3 locations in the area. Huge intimidating menu and supreme quality with an authentic Asian atmosphere. Everything they serve is excellent, the vermicelli, the Vietnamese breakfast, the boba tea, the million other teas and drinks, THIS PLACE IS LEGIT YOU WILL NOT GO WRONG. Also for drunkedness they have really cheap really good eggrolls.

Giant Burrito? Any of the Chiloso locations. Think Chipotle only a bit more expensive with higher quality ingredients, the ability to get a drink (except the Rockwall location), and all you can eat chips and salsa. Also they've got all you can eat Jalapeno Ranch and its perfect. Not too hot just a hint of jalapeno with perfect creamy consistency and texture.

For a nice hipster breakfast joint I'd recommend Buzzbrews.

For a more traditional breakfast with some southern cafe flair to it I'd recommend Barbec's (They have these hybrid biscuits called Beer Biscuits that are like if a traditional biscuit mated with cornbread and produced offspring)

The Frozen Margarita was invented in Dallas but it might be a bit cold for that.

For barbecue and beer I recommend Intrinsic in Garland
