$22.60 for 2 hot dogs, 1 drink and chips. Not bad value wise
For the fried stuff they have an issue with heat. The croquettes and fries weren't hot. If they were they'd be pretty good. They have slimmed down the hot dog menu somewhat and now also sell more standard Japanese dishes so may have bough a new fryer.
The ones with Frankfurt's are much better. Get Frankfurt's.
Dog Dog Japon is in the same arcade as Oiden and Mappen. We noticed they gave us Mappen/Oiden moist towelettes too...so we wonder if they're the same company or if they just have stolen a whole stack of Mappen/Oiden towelettes.
If they're the same company then between Menya, Mappen, Oiden (although never eaten there), Chanoma, Tenkomori and possibly Dog Dog Japon that's basically 90% of our CBD Japanese spend going to one company. Although Chanoma has hot dogs so we're not sure why they'd compete with themselves (having said that Mappen and Tenkomori compete with Menya). Branding is totally different to the rest of the group though.
There are a couple of older guys who always seem to be there and we kinda imagine them as the owners who are pursuing their dream (but this is also unconfirmed).
