I took Bus 90 from Kinderdijk and reach Zuidplein, which is a shopping complex with Metro station.
The Metro ticket is quite interesting, as you don't buy your ticket by destination, but you pay EURO 3.50 for a 2 hour pass. I choose to visit Delfshaven, as it is an interesting old neighborhood. This street is filled with immigrants, mostly african and middle easterner; which means good variety of restaurant, especially kebab. The buildings here are fairly interesting, but still rows and rows of brown-colored buildings (perhaps I am not the guy to appreciate architecture). I walk towards central, and trail of immigrants had lessen along the way. Interestingly, there are rows of Chinese restaurant near the train station, mostly of Cantonese origin. Finally I stop at a Kebab (Doner) stall, which offer a kebab burger for UERO 3+ or EURO 5+ for set meal (with fries and drink). I opt for the wrapped kebab (mayonnaise and hot sauce is free, an good) , which is really full, but the meat is not necessary tasty.
Rotterdam is a big city (they have Metro and Tram), yet might not be an interesting one (perhaps I didn't do enough research), and I didn't have time for Den Haag. Perhaps I dislike big city, just rows of shops and tiring walking around; and the restaurants here are expensive, so I can't indulge myself in great gastronomy adventure. Most of the shop here doesn't close by 5pm, but in comparison, Den Bosch seems like a cozier place to visit. It makes me wonder what we really enjoys during our travel? I would say trying now new food (but internationalization of restaurants means you can eat almost any type of food anywhere, which make the experience less satisfying), view the magnificent scenery (sadly, most of these places are overcrowded or too expensive) and finding the hidden gem (which remain hidden, or became too popular). In a certain sense, which visiting the local grocery and trying to live a different live in a different city seems more interesting at times, but this cannot be experience with just over one week in a place and staying in hotel. Perhaps my concept about traveling is starting to change. I usually enjoy hiking trip: nature, beautiful scenery all the way and no city hassle or thinking what to do next.
Finally took a train back to Den Bosch for EURO 16, which need to switch at Utrecht Central. The transportation cost of the day is pretty costly, add up to EURO 42. Perhaps cycling around Den Bosch to the next towns are better value for money, for EURO 7.50 per day.
