Sandwich Cafe near Tokyo Tower

This morning cafe near Shinjuku Gyoen sells BLTC and BLTE sandwiches with coffee. You can order the BLTC and BLTE split half and half, both made with plenty of vegetables and egg. It opens at 9 a.m., but waits of at least 30 minutes after ordering are possible, so QR ordering or calling ahead helps. The seating inside is very cramped.
