My favorite ramen place among the ones we tried on this trip to Tokyo is Ichiran (一蘭)! I love how you could customize the soup, the noodle, and the ingredients to your likings.
Self-serve vending machine where you purchase your ticket. 
Next, check to see which seats are available. 
Studying instructions in my cubicle. 
You can customize how you like your ramen. For example, how thick you like your broth to be, how you like the noodles cooked, and how much garlic and what kind of green onions you like, etc. 
My ramen with ‘white’ green onions and lots and lots of garlic! Love the flavor!!
Brian chose ‘green’ green onion and extra spicy. 
Please help yourself with the water. 
You are in your individual cubicle with dividers. A bamboo curtain separates you from the kitchen. You are supposed to concentrate on your ramen 100% without distraction. 
All done! 
On the bottom of the bowl we saw the words, この一滴は最高の喜びです, which means, “This one drop is the greatest of joys” (or, “good to the last drop”). Indeed.
