I have gone to the Tinjo several times during the last 5 years and I have always like it... This last time I went with my family and we had an ok time. Service has gone down a bit.. I´m not sure if this was because of the time of the year (December) or just the fact that they are very popular and the restaurant is usualy full.
The last 2 times I´ve been there the waitresses have done an ok & poor job. One time the lady was too casual and did not know much about the dishes served, lack of training?? The second time I was located in one of the tables in the big room to at the left side of the restaurant (right when you come in to your left) and the service was ok but at times I felt we were unatended.
The restaurant has a good menu, same one with no changes since long a go and prices are expensive, we paid around $100 for 3 adults with small entries, main dish, dessert and drinks...
The atmosphere is good, music is ok and at a good volume but the lights might bee too down when it comes to check the menu (at least at the big room I mentioned).
I will recommend the visit still, I hope they watch their business because my experience is no longer the same every time. It worth to go for a nice friends, family or date night but if you are looking for a cheap restaurant this will not be good for you. oh! and try to reservate a table first, here the number +(506) 2221-7605
