Yup, I found the best place for Tokyo style ramen in Bogota. The restaurant is located at Carrera 11 and Calle 98, overlooking the little park between 11 and 12. (*** update January 5, 2016 **** Telephone number is 609 09 59. They are open Monday-Saturday from noon to 9:30 p.m. and on Sundays/holidays from noon to 6 p.m.)
They must cater to salarymen because they aren’t open for dinner on Saturdays, nor are they open on Sundays.
I enjoyed the soft tofu appetizer, the kontaksu (fried pork or chicken cutlet, here served on fried noodles as light as air), and the calamari which were soft and tender.
Some people would probably like me to keep this place a secret. Ooops.
