I've visited Giant Coffee many times, and I'm finally getting around to writing a review. I think my last experience pushed me over the edge to finally writing it.
Whenever I'm in Phoenix and looking for coffee I usually head to Giant. Nothing against Lux or Lola just down the street, but Giant is more focused on their product. Giant has a standard of sourcing great coffee and using high quality product.
On my last visit I ordered a cappuccino and it was nearly perfect. Warm, but not too hot. Smooth by still having a strong espresso dynamic. Perfect balance. Before I left I went up to the counter to order a cup of coffee to go. They have a great setup for to-go coffee. They brew great coffee in large quantities so that those who are on the go can get a great cup of coffee quickly. The barista was very sweet and informed me the coffee had been sitting for a while. She said it would be a few minutes and she would brew me a fresh pot. It was the middle of the week, and I think there were only two other people in the shop, who had already ordered drinks. How easily could she have served me that mediocre cup of coffee? Very. But this showed her integrity and pride in their coffee to brew a whole new batch just for me. It's the little things like that that impress me the most.
I recommend this coffee shop for anyone in the downtown Phoenix area. Not to mention the cool sliding glass doors in front that they open up when the weather is nice. There's some comfy chairs and cook wooden tables to sit and enjoy the weather from.
PS. The clothing boutique next door is also cool. I found a great hat there.
