The Mistral Bleu Train Bar is a distinctive establishment in Tokyo's bustling Roppongi neighborhood, notable for being housed within an actual train car that appears to burst from the side of the ROI Building. This unusual setting taps into Japan's fascination with trains, offering a novel experience that stands out amidst the area's typical skyscrapers and commercial centers. It's a place where the physical environment itself is a major part of the attraction, drawing both locals and curious tourists seeking something off the beaten path.
Visitors consistently praise the bar's unique atmosphere and its ability to foster social interaction. The cozy interior, which accommodates around 30 people, encourages patrons to mingle and make new friends. Reviewers often highlight the tradition of ringing a bell to buy shots for everyone, contributing to the convivial mood. The decor, featuring walls plastered with photos of past patrons and ceilings covered in currency from around the world, adds to its quirky charm. The music selection, primarily classic rock and heavy metal from the 90s and early 2000s, is frequently mentioned as a nostalgic draw for many.
For a comfortable visit, plan to spend about 1-2 hours here, allowing enough time to soak in the atmosphere and engage with other guests. The bar is best visited in the evening, as it transforms into a lively spot after sundown. Don't expect elaborate craft cocktails or a wide selection of beers; the drink menu is straightforward, focusing on simple options like Heineken and shots. This simplicity is often seen as part of its unpretentious appeal. It's a cash-friendly establishment, so having some Japanese Yen on hand is advisable.
Getting to the Mistral Bleu Train Bar is straightforward. It is located only a few minutes' walk from Roppongi Station, which is served by the Tokyo Metro Hibiya Line and Toei Oedo Line. Upon exiting the station, look for the ROI Building; the train car is an unmistakable feature on its exterior. Public transportation is highly recommended, as parking in Roppongi can be scarce and expensive.
A common point to be aware of is the bar's small size. While this contributes to its intimate and social atmosphere, it also means it can get very crowded, especially on weekends or peak evenings. Some visitors have noted that the close quarters might not appeal to everyone. To mitigate this, consider visiting earlier in the evening or on a weekday if you prefer a slightly less packed experience. Despite the crowd, the friendly staff and unique environment generally ensure a positive experience.
