Hey, just a thought on putting the espresso machine on the back counter. It's great for people to see what you're doing, but likewise, your back will be to the customer, and that's not a great situation - especially since most barista's and customers always have a little chit chat. Then, when you're serving, you're moving the entire drink across.
It's up to you but I have yet to see this work well anywhere. Also, many times it's very busy and you don't want them to see everthing :decaf:
I like your idea a lot, but it's going to be a challenge logistically.
For the countertop, 36" is good and you can get a fridge undernieth - make sure to spec out the fridge. Also, we made a big mistake - make sure there is a floor drain for the espresso machine right under the machine, and also put a floor drain directly in back of the ice machine. I thought I could save a few bucks by using the same floor drain, and just plumbing the ice machine to the espresso drain. Well, I didn't realize you have about 6" of fall from the ice machine drain to the floor, so plumbing it over 4 feet, it constantly clogs because there's no fall. Off topic, but a lesson from me to you
