Quick, affordable udon with lots of choice before an O2 event, but hygiene and consistency issues at this branch mean results can vary.
Why it gets a D for overall quality
Marugame delivers fast-casual convenience and decent value as a pre-show pit stop inside The O2, with praise for fresh udon and tempura when conditions permit. However, documented food safety issues including undercooked chicken and hygiene concerns combined with notable quality swings between visits and during peak rushes create meaningful risk. The canteen-style format and venue location prevent this from being a standalone destination, and operational inconsistency undermines reliability for repeat visits.
Restaurant Summary
Inside The O2, this canteen-style spot buzzes with pre-show energy, trays sliding along the counter while cooks assemble steaming bowls of udon. Fans praise the speed and value when the line moves, and one diner noted it as a "brilliant value pitstop before your show." Still, experiences diverge—some report messy stations and hit-or-miss cleanliness during rushes. The cooking leans classic udon with a few playful twists—think kimchi or even a carbonara-style bowl—so it is comfort-first Japanese with modern detours. When fresh, prawn tempura eats light and crisp, tonkotsu broth is soothing, and katsu curry hits that pre-concert craving. On busy nights, though, consistency wobbles: a few diners found tempura served too cool or noodles over-firm, and delivery orders occasionally missed items. Families will find this very kid-friendly. The menu includes a dedicated Kids' Bento lineup (kake udon, teriyaki chicken, popcorn chicken), plus mild broths and rice bowls that young eaters recognize. If your child is sensitive to spice or texture, stick to simple kake or curry udon and skip the more adventurous specials like fusion twists that may divide opinions.
