Any vegetarian options or can I modify the ramen to exclude meat?

Yes there's 1 vegetarian/vegan mushroom based option. You can opt out of the egg to make it vegan. It's delicious!

There is one vegetarian option and yes you can also exclude meat from the other bowls. I've tried the veggie option, a meat option and a meat option with no meat. All three tasted good with veggie option being my favorite. If you are looking for pure veggie, like if if wouldn't want meat based broth, then you'll have to go with the only veggie option. You can also exclude egg if you prefer so.

You can exclude meat if you'd like

Yes. There are like 4 ramen bowls on the menu, one of which is a mushroom bowl.
