drink or eat (something) with a loud sucking noise.
Have you been to TENKOMORI? It’s like you’re in an actual Osaka or Tokyo ramen shop. Tenkomori is typically Japanese – ruthlessly efficient - with its in-out, no-fuss system. You start by picking your soup base and noodles, then you move along to help yourself to as many deep-fried items your coronary arteries can handle. Further down, you pick up some toppings, pay and then slurp away.
Trading until late night.
