Try this in emacs -Q

(defvar bar-mode-map (make-sparse-keymap)
  "Keymap for Bar mode.")
(defvar bar-menu-map (make-sparse-keymap "Bar")
  "Keymap for Bar menu.")

(define-key bar-mode-map [menu-bar bar]
  (cons "Bar" bar-menu-map))
(define-key bar-mode-map [remap switch-to-buffer]
  'bar-buffer)

;; This way, the key binding shows incorrectly in the menu.
(define-key bar-menu-map [bar-buffer]
  '("Bar Buffer..." . bar-buffer))

;; This way, the key binding shows correctly in the menu.
;;(define-key bar-menu-map [bar-buffer]
;;  '("Bar Buffer..." . switch-to-buffer))

(define-minor-mode bar-mode "Bar mode")

M-x bar-mode

You'll see the bad menu item (bad key-binding description) in menu Bar.

Now execute the commented code. The menu item is now as it should be.

Interestingly, this apparently has something to do with the minor-mode map,
because similar code using the global map does not have the same problem. It
shows, however, no binding at all in the menu item.

(defvar foo-menu-map (make-sparse-keymap "Foo")
  "Keymap for Foo menu.")

(define-key global-map [menu-bar foo]
  (cons "Foo" foo-menu-map))
(define-key global-map [remap switch-to-buffer]
  'foo-buffer)

;; This way, there is no key binding in the menu.
(define-key foo-menu-map [foo-buffer]
  '("Foo Buffer..." . foo-buffer))

;; This way, the key binding shows correctly in the menu.
;;(define-key foo-menu-map [foo-buffer]
;;  '("Foo Buffer..." . switch-to-buffer))
