I don't know if the contents of a bowl of ramen change regionally in Japan, but here in Sapporo, ramen comes in a HUGE bowl that consists of a piece of pork, an egg, bean sprouts, bamboo, and ramen noodles. It's considered rude not to finish the entire bowl, so we usually eat ramen when we're really hungry. It's also perfectly acceptable to slurp your noodles, which has taken some getting used to on my part.
I have to admit, eating a huge steaming bowl of ramen on these hot summer days has been a challenge, but it's just so good! I'm sure it's going to be even better during the snowy months!
