We stumbled upon The Lucky Bean on our walk with our pooch from the Eldorado Hotel down through the Guadalupe and Rail Yard Shopping Districts. They not only have patio dining, they'll even let you take your pooch inside! This little coffee nook is around the corner off to the side of the cavernous room that takes you in through the back way to the Sambusco Shopping "Mall". Conversely, you can enter Sambusco through the front and continue on through it until you come to the door into the cavernous room. Either way, there is nothing that shouts to you, "this way to the coffee shop". I do wonder what they use that big room for.
We ordered a large Iced Mocha to go and it was plenty for both of us to quench our thirst and elevate our energy level. It had the most dark chocolate syrup of any mocha I've ever had, and the coffee was a rich dark roast.
Their food menu is fairly limited with breakfast burritos, and turkey, ham and cheese, tuna and egg salad being pretty much the selection as far as sandwiches go. There are about 4 tables inside and 3 for outdoor dining. Both of the people working the place seemed a bit spacey, so be patient and they'll be friendly and treat you right.
We really did like being able to take our dog in; since we went back outside after receiving our order, I don't know if you'd have to go back around the corner to the big room or even outside to eat, or if they would let you sit at one of their indoor tables with your dog to eat.
Continuing on into Sambusco, we also found a pet supplies boutique where we picked up a couple of items for the doggie, including a spray foam that is supposed to freshen breath. I don't think the signage on the Sambusco side of the building has the name of either of these shops, so I hope people manage to find them.
