1. El Camino 
El Camino Just started offering brunch. Starting at 10 a.m. on Saturday and Sunday, offerings include black forest ham with charro beans, roasted peppers, fried egg and salsa verde. They also have sticky buns to die for. Read Louisville.com's review of El Camino here , and maybe you can get a margarita instead of a mimosa. We won't tell.
2. Seidenfaden’s 
Yes, the bar. Most Sundays Seidenfaden’s hosts a local food truck for brunch-y goodness. Previous guest appearances have been made by the French Indo-Canada Food Truck, Holy Mole, and Grind. You could feasibly just stay at Seidenfaden's until they close Saturday night, go have a few cups of coffee at a Waffle House or something, and then come back for breakfast. You can read more about Seidenfaden's brunch here. 
Open at 8 a.m. weekdays and 10 a.m. Saturdays, Atlantic No. 5 is fresh and beautiful, briskly decorated. Their daily array of house-made pastries are the perfect hung-over nibble, and their steel cut Irish oatmeal and fruit is healthy sustenance for the calorie conscious among us. Their savory pies make a great brunch or lunch pick.
