In business for over a century, La Bombonera Cafe has been a local institution for decades. It caters today to a mixed crowded of locals and tourists, as the restaurant is referenced in every guidebooks. It is a cafe-type of restaurant, a good choice for breakfast and for light, unpretentious meals.
The ambience is rustic and the service informal. I came here for breakfast (that seems to be a must-do experience in Old San Juan). Do not expect a large choice on the menu, they serve Puerto Rican-style breakfast, usually made of a cup of coffee with a pastry or a sandwich. The specialty of the place is the "mallorca", a Spanish Danish, or a kind of sweet bread topped with powder sugar and filled with your combination of butter, ham and cheese. The place is also renowned for its coffee, apparently brewed into coffee-machines from Cuba in service for over a century. To my taste, coffee was great but be aware by ordering coffee they serve you "coffee with steamed milk" or cafe con leche if you will. Fresh squeezed orange juice is another item on the menu worth trying.
As said, breakfast at La Bombonera is an Old San Juan's classic, worth for checking out the place and the crowd better than for the good but not memorable food-experience.
Located in Old San Juan, where it seems no restaurant opens nowadays but posh and expensive "fusion" and "eclectic" restaurants, El Jibarito is a terrific landfall for those looking for some good traditional Puerto Rican food.
The place is on the guidebooks and it is crowded with tourists and locals. Don't expect anything else than good food served in a rustic atmosphere. On the menu plates from Puerto Rico traditions such as sancocho, pernil the cerdo, camarones a la criolla, arroz con abichuelas, arroz con gandules and mofongo. I was totally satisfied of my lunch experience and found out with regret the same night, arriving past closing time, the restaurant at dinner closes at 9:00 pm. All in all, a great choice for a Puerto Rican traditional meal in Old San Juan.
I noticed the Restaurant has a colorful website that I am attaching for reference.
