I chatted with owner and he is friendly Japanese man who stayed in the states for 36 years.
He was invited by U.C. Berkley since he was prominent athlete. Several years ago, when he came back to Japan with his wife, he soon started preparing to open this place. While you are eating you can also enjoy talking with him. ( If he was not too busy.)
The hamburger is juicy, real one. Salt & pepper and special sauce he made... , so you would not need sauce or ketchup. Be careful when you eat since the sauce might come out and make stains on your cloths.
Char-grilled hamburger is flavorful !

2-34-11 Kitazawa, Setagaya-ku, Tokyo
From Shimokitazawa station, exit to North side. ( You will find Peacock Store )
Take a right and when you see Yokohama bank on your left, turn right.
At the end of that street, turn left. ( On your left corner, there is traditional rice cracker shop.)
Keep on going. FRISCO will be on your left in 1 or 2 min. ( The entrance is very difficult to find since the sign is in between shops and the actual door to the shop is deep inside the alley.)
